Help with Installing Discount Coupon

[anggora]

I don't know what I did wrong.

I have installed it from the Order Total Module, and when I go to the Gift Certificate/Coupon, I got this message:

"1054 Unknown column 'coupon_zone_restriction' in 'field list'
in:
[select coupon_id, coupon_code, coupon_amount, coupon_type, coupon_start_date,coupon_expire_date,uses_per_user,uses_per_coupon,restrict_to_p roducts, restrict_to_categories, date_created,date_modified, coupon_active, coupon_zone_restriction from coupons where coupon_active='Y' and coupon_type != 'G' limit 0, 20]
If you were entering information, press the BACK button in your browser and re-check the information you had entered to be sure you left no blank fields."

Help!

Looks like you have upgraded to v1.3.8 and do not have the field coupon_zone_restriction in the coupons table ...

How did you do the upgrade?

Did you upgrade your database?

I didn't do the upgrade so I'm not sure how it got upgraded to the v1.3.8 and not sure if the database has been upgraded or not.
How can I found out?

I'm very new to zen cart and if you could provide me with a few pointers, that would be awesome!

Thank you!

You might want to read through the /docs directory that came with your Zen Cart software ...

If you do not have this, you can download a clean Zen Cart v1.3.8 to obtain this ...

NOTE: Before upgrading, you will want to backup your database first ...
